GUDGEON FOR WlNDOW-SHADE ROLLERS.

SPECIFICATION forming part of Letters Patent No. 325,422, dated September 1, 1885.

Application filed January 26, 1585. (N model.)

To aZZ whom it may concern: diameter of the head being somewhat less Be it known that I, JOHN LINES, of Wathan the diameter of the recess in the bottom terbury, in the county of New Haven and of the cup.

This striking of the flange f upon the 70 2O gudgeon. outside of the cup makes a very strong con- This invention relates to an improvement nection,because of the extent of the flange on in the gudgeon which forms a pivot upon one side and the head upon the opposite side, which shaderollers turn, and to that class in and avoids the use of solder. It is so strong which the gudgeon is attached to a cup can that separation of the gudgeon from the cup 75 structed to be set on over the end of the roller, is impossible except by the destruction of one and is an improvement upon the invention or the other. The projection on the outer end for which Letters Patent N 0. 298,611 were of the cup is desirable,but not essential, and granted to the assignees in this appiication, is substantially the same as that shown in the the invention relating especially to the methpatent before referred to. 3 0d of securing the gudgcon to the cup 5 and the I am aware that gudgeons have been made invention consists in constructing the gudgeon by constructing the cup with a concentric rewith a head upon one end and an enlargement cess upon its inside and the gudgeon with a immediately under the head, the body of the head, the gudgeon introduced from the inside gudgeon introduced through the cup from the through the central opening in the cup, and 8 5 5 inside to bring the head to a bearing thereon, so that the head rests in the recess, as seen in the enlargement extending through the holein Patent N 0. 298,611, and therefore do not the cup,the projecting portion of said enlargebroadly claim such a construction of gudgeon; ment then struck down onto the outside of but in the construction described in that patthe cup around the hole, as more fully hereincut the head of the gudgeon is secured in the 0 after described. cup by solder introduced into the recess sur- A represents the cup, which corresponds in rounding the head.

I am also aware that the gudgeon has been riveted into the head by constructing the rivet with a shoulder distant from its inner end so far as to permit that inner end to pass through the-central opening in the cup, and then riveting down the inside end; but such riveting upon the inside makes but a slight security.
